SAN MATEO, Calif., March 25, 2026 /PRNewswire/ -- Talphera, Inc. (NASDAQ:TLPH), ("Talphera"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced the acceptance of two abstracts for presentation at the 31^st Annual International Conference on Advances in Critical Care Nephrology: AKI & CRRT 2026 to be held March 29-April 2, 2026 in San Diego.

Poster Presentation 1

Title: A Randomized, Placebo-Controlled, Multi-Center Study Of The Safety And Efficacy Of Niyad In Patients Undergoing Continuous Renal Replacement Therapy (CRRT) Who Cannot Tolerate Heparin Or Are At A Higher Risk of Bleeding

Presenter: Kayla Adler

Date and time: Sunday, March 29, 5:30 – 7:30 PM

Session title: Clinical Research in AKI 2

The poster will highlight the key components of the NEPHRO-CRRT study design, currently enrolling patients in the registrational study. There is an unmet medical need for safe, effective, and simple-to-use regional anticoagulants for use during CRRT. Nafamostat has desirable properties and extensive user experience as a regional anticoagulant for over three decades outside of the US. The NEPHRO-CRRT is an ongoing registrational study to evaluate the safety and efficacy of nafamostat for its potential approval in the US to address this unmet need.

Poster Presentation 2

Title: In Vivo Assessment Of Nafamostat, A Novel Regional Anticoagulant In a Porcine Model AKI And CKRT

Presenter: Kayla Adler

Date and time: Monday, March 30, 6:00 – 8:00 PM

Session title: Clinical Research in AKI 3

This study characterized the pharmacokinetics of nafamostat and its effect on post-filter and systemic Activated Clotting Time (ACT) across different membrane types in a porcine model of AKI receiving CRRT. When administered pre-filter, over 95 percent of nafamostat was removed by the hemofilter, resulting in the median systemic exposures of less than 5 percent of the pre-filter exposure. There was a minimal effect on the systemic ACT when the post-filter ACT was less than 275 seconds. The NEPHRO CRRT registrational study of nafamostat is targeting a post-filter ACT of 175 to 225 seconds, which is expected to provide sufficient extracorporeal anticoagulation while minimally affecting systemic ACT. In conclusion, nafamostat has unique PK and PD properties, making it a suitable candidate for further evaluation as a regional anticoagulant in CRRT.

"While we are currently enrolling patients in our NEPHRO-CRRT registrational study, based on use in Japan and South Korea for over three decades, we continue to believe nafamostat will be an effective regional anticoagulant for use during continuous renal replacement therapy (CRRT), and we're excited to share the poster presentations at AKI & CRRT 2026," stated Dr. Shakil Aslam, Chief Medical Officer of Talphera. "The current anticoagulants being used for CRRT are not ideal and have many disadvantages. If approved, nafamostat would become the first regional anticoagulant approved by the FDA for use during CRRT," continued Dr. Aslam.

About the NEPHRO CRRT Study

The NEPHRO CRRT Study, which has received central IRB approval, is designed as a prospective, double-blinded trial to be conducted at up to 14 U.S. hospital intensive care units. The study will enroll and evaluate 70 adult patients undergoing renal replacement therapy, who cannot tolerate heparin or are at risk for bleeding. The primary endpoint of the study is mean post-filter activated clotting time using Niyad versus placebo over the first 24 hours. Key secondary endpoints include the mean post-filter activated clotting time over 72 hours, filter lifespan, number of filter changes over 72 hours, number of transfusions over 72 hours and dialysis efficacy (based on urea concentration) over the first 24 hours.

About Niyad and Nafamostat

Nafamostat is a broad spectrum, synthetic serine protease inhibitor with anticoagulant, anti-inflammatory and potential anti-viral activities. Niyad® is a lyophilized formulation of nafamostat and is currently being studied under an IDE, as an anticoagulant for the extracorporeal circuit, and has received Breakthrough Device Designation Status from the FDA. Talphera's registrational study of Niyad is named the NEPHRO CRRT (Nafamostat Efficacy in Phase 3 Registrational Continuous Renal Replacement Therapy) study. An ICD-10 procedural code, XY0YX37, has been issued for the extracorporeal introduction of nafamostat. The ICD-10 code is a specific/billable code that can be used to indicate a procedure. LTX-608 is a proprietary nafamostat formulation for direct IV infusion that may be investigated and developed for the treatment of acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC), acute pancreatitis or as an anti-viral treatment, amongst other potential targets.
